NAD Cd Player 510

[xicomos]

Hi all,

My NAD Cd Player 510 stop working.
When I insert a CD only "No Disk" is present. I can't heard any spinin od the CD.
Does anyone have the service manual of this cd player or knows how to repair this problem.
Thank you in advance.

if cd turns , it is surely the head laser , else looks for a switch for good position

what laser is ?

The problem is it doesn´t start to spin. Imediately afer I close the cd tray, it apears the "no disc" message. Can be a motor drive problem ?

I too have a 510 with the same symptom.
A friend of mine saved it from certian death curbside.
In great shape tho.
I replaced the laser assy (a sony kss model) and that didn't help.
I am also in need of the service manual if anybody has one to share or sell. Its been on the shelf now for a year or so cause I have a couple of other cdps but I would like to fix it and do some tweeking on it.

The original laser assy for the 510 is a Phillips cdm12.1 ,you can replace it with the Phillips vam 1202 , easy to find on the internet and not expensive.

Hi all,

Sorry for the delay.

The value for R114 is 10k Ohm with 5% tolerance.
The value for R110 is 1 Ohm with 0.1% tolerance.

I hope this help.

do you think it could be possible to also look for the R111 for me. I think I might have burned it trying to fix the new laser. Thanks a lot!

Do you have the service manual of the CD 510 ?

Hi,

I also have the same issue - when I put CD into player laser is blinking, focusing but motor doesn't run.
Have you any idea what could be wrong ?
